If you modify "VbeShim.asm", then please re-run "VbeShim.sh", for
updating "VbeShim.h".

The DEBUG macro at the head of VbeShim.asm is commented out:

  ;%define DEBUG


So the string "Unknown Mode" is not used.

Side note, running VbeShim.sh on Fedora 30 I get:

The nasm packaged is:

$ nasm -v
NASM version 2.13.03 compiled on Feb  2 2019

While NASM 2.12 is documented here:

https://github.com/tianocore/tianocore.github.io/wiki/Nasm-Setup

Should I downgrade it?
